Types of Skin Cancer

Skin Checks that don't miss a thing!

Melanoma is a type of skin cancer that develops from the pigment producing cell, melanocytes. It is the most dangerous form of skin cancer, most often caused by ultraviolet radiation from sunshine or tanning beds which trigger mutations that lead the skin cells to multiply rapidly and form malignant tumors.

They usually occur on parts of the body that are overexposed to UV rays, however, in some cases it can start in parts of the body that have never been exposed to the sun, such as the nervous system. While it is the least common of the skin cancers if left untreated it can quickly spread to other parts of the body and have fatal results.

Warning Signs – the ABCDEs of Melanoma:

Melanomas may look like a mole to start with but invariably changes over the coming months. Identifying changing spots is very important in early identification. They are usually seen rather than felt, there may be some itching. Superficial spreading melanoma is the most common type and follows the ABCDE of clinical assessment.

Biopsy at Bondi Skin Cancer Clinic

What is a Skin Biopsy?

If one of our doctors at Bondi Skin Cancer Clinic thinks that a suspicious area on your skin might be cancerous, they will take a sample for further examination. Based on the information received about the biopsy they will then plan a treatment strategy appropriate for the cancer type. There are different methods employed for this, depending on the size, type and location of the affected area.

Skin biopsies are done using a local anaesthetic so you should not feel any pain during the biopsy. Any biopsy is likely to leave a scar, however our doctors do work to ensure any scarring is a minimal as possible. Please ensure to talk to the Doctor about the type of biopsy required and possible.

Shave biopsy

The doctor “shaves” the top layers of the skin with a specialised surgical blade which takes the top layers off the skin. This type of biopsy is useful in diagnosing basal or squamous cell skin cancers. It would not be beneficial in diagnosing melanoma as the sample would not be thick enough to measure how deeply the melanoma may have invaded the skin.

Punch biopsy

A tool that looks like a tiny round cookie cutter is used in this procedure. It is used to take a deeper sample of skin using a small diameter.

Incisional and excisional biopsies

These techniques are used where the doctor may need to examine a tumour that may have grown deeper in the layers of skin. Incisional is where they remove a portion of the tumour, removal of the entire tumour is called an excisional biopsy and is usually done when a melanoma is expected. These can be done with a local anaesthetic.

Examining the biopsy samples

All skin samples are sent to pathology for further examination and diagnosis by a specialist.
